When superelevation transitions occur within or adjacent to vertical curves, the profile of the edge of the road is sometimes distorted into shapes that are visually unpleasant or cause severe frainage problems, particularly on freeways or other wide roads. Such problems can be easily and quickly solved by simple algebraic methods that need no plotting of edge profiles to scale or resorting to curves more complicated than standard parabolic vertical curves if one takes advantage of the inherent simplicity of standard highway geometry. Methods for doing this are developed and demonstrated with a numerical example./Author/
